成唯識論演祕 4.492

4.492

此釋意云：隨緣何地所引果識，第七俱受，即與先世引業受同。何所以者？緣彼引業所感果故。疏云相應是隨順義，若與彼業受不隨順，即不能緣彼業之果。

The intention of this explanation is: Whatever plane's resultant consciousness it takes as object, the feeling associated with the seventh is identical to the feeling of the projecting karma of the previous life. Why is this? Because it takes as object the result produced by that projecting karma. When the Commentary says 'associated', it means 'in conformity with'; if it did not conform to the feeling of that karma, it could not take the result of that karma as object.
